ROTARY-CUTTER OR PINKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 691,702, dated January 21, 1902.

Application filed November 12, 1900. Renewed June 22,1901. Serial No. 65.646. (No model.) I

To all whom it may concern.-

Be it known that I, THOMAS F. HAGERTY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Rotary-Cutter or Pinking Machines, of which the following is a specification.

This invention relates to improvements in rotary-cutter or pinking machines-that is, a machine intended to pink or scallop clothor other fabric; and the main object of my invention is to provide a novel device for adjusting the rotary anvil with relation to the rotary cutter, so as to compensate for the wear of the cutter.

Another object of my invention is the proand practical improvement.

To attain the desired objects, the invention consists of a pinking machine embodying novel features of construction and combination of parts,substantially as disclosed herein.

In the drawings, Figure 1 is a perspective View of my improved rotary-cutter or pink- 'ing machine. Fig. 2 is an end view of the machine with thecrank and the lower gear removed from the anvil or driving-shaft. Fig. 3 is a detail view of the eccentric sleeve or bearing for the driving-shaft.

, Referring by letter to the drawings, A designates the frame of the machine, which is provided with the pair of upper bearings B for the reception of the cutter-shaft 0, upon whose outer end is mounted the rotary cutter D, and upon the other end of the shaft is the gear-wheel E. The frame A is mounted upon the base F, whose front portion is broader than the rear, from which depends the rightangled arm G, carrying the binding-screw H to clamp the machine to a table or suit-able support. Mounted in the pair of lower openings J of the frame is the eccentric bearing or sleeve K, or rather the cylindrical sleeve with the circular channel L made eccentricall'y therethrough. This bearing is held at any desired adjustment by means of the setscrew M and is further provided with the flattened portions or surfaces N intermediate of its length in order that the bearing can be easily turned, thus adjusting the rotary anvil O, mounted upon the driving-shaft P, which has secured to its other end the gear Q and the crank R, both of which are formed integral, this being a novel point in the construction of my machine.

A shelf or table S, through which the upper surface of the anvil passes, is secured to the side of the frame by means of a screw T, and to prevent the cloth from becoming entangled in the machine I employ the guide U.

When the rotary cutter and anvil are in contact, the two gears, whose pitch-line is the same as the diameter of said cutter and anvil,

' are left sufficiently apart, so that the teeth will not mesh, thus leaving sufficient space to provide for the wear ofthe cutter under all required adjustments.

From the foregoing description, taken in connection with the drawings, the operation of my machine is readily understood and its advantages fully. appreciated; but, briefly stated, it is as follows: According to the number of the thicknesses of cloth to be scalloped or pinkedthe eccentric bearing is adjusted, thus raising or lowering the rotary anvil with reference to the cutter. When the desired adjustment is attained, the set-screw is fastened and holds said bearing in place while the crank is turned, and the cloth passes over the table between the cutter and the anvil. The two pairs ofbearings, or rather the top bearing and the openings for the eccentric bearing, are drilled so as to'bring the shaft and bearing in perfect alinement with relation to each other, and the construction of-the frame and base forms one of the most simple and cheap methods yet employed. By this arrangement I am enabled to readily adjust the anvil with relation to the cutter by a slight movement of the eccentric bearing, and from the constructionand arrangement of the parts I produce a very simple, durable, and cheap pinking-machine which is useful and practical.

I claim-- 1. In a pinking-machine, the combination of a frame, a cutter-shaft carried in the frame, an eccentric bearing mounted in the frame below the cutter-shaft, a driving-shaft mounted in the said bearing and geared with said on tter-shaft, and a rotary anvil mounted upon said driving-shaft below said cutter.

2. In a pinking-machine, the combination of a frame, mounted upon a base, a shaft carrying a rotary cutter mounted in the upper portion thereof,an eccen tric bearin g or sleeve, a driving-shaft mounted in said bearing below said cutter-shaft and geared with the same, a rotary anvil mounted upon the driving-shaft, and means to hold the eccentric hearing at its proper adjustment.

3. In a pinking-machine, the combination of a frame, an upper bearing formed in said frame, a cutter-shaft mounted in the bearing, a gear carried upon one end of the shaft, a rotary cutter carried upon the other end, an eccentric bearing mounted in the frame, a driving-shaft journaled in said bearing and geared with said gear of the cutter-shaft, a rotary anvil mounted upon said driving-shaft directly below the rotary cutter, and a table mounted upon the frame between the cutter and the anvil.

4. In combination with a pinking-maohine, a cutter-shaft, a driving-shaft, an eccentric sleeve or bearing carrying said d riviug-shaft,

' a crank and gear formed integral with each other and mounted upon the driving-shaft, and a rotary anvil mounted below the cuttershaft upon the driving-shaft.

5. In combination, a pinking-machine c011- sisting of the base having a broad front and a narrow rear portion, a right-angled arm depending from said base and carrying a clamping-screw, a vertical frame formed integral with said base, a pair of bearings formed in the upper part of the frame, and a pair of openings formed 'in the lower part, a cutter shaft having a gear and the cutter mounted in the upper bearings, a sleeve provided with a channel the full length thereof eccentric ally mounted in the pair of openings of the frame, and a driving-shaft mounted in and carried by said sleeve having an anvil mounted upon one end and a crank and a gear upon the other end.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS F. IIAGERTY.
